Senior Software Engineer (Founding Team) - TypeScript, NestJS, NextJS, GCP

Location: West London, 3 days a week on site

Incubated: The security of a startup within a global business

Join a startup redefining music’s role in health and wellbeing.

We're partnered with an incubated, well-funded startup within the field of audio technology as they build out their Founding Team. They're blending music, AI, and technology to enhance mental and physical wellbeing.

They're exploring music as a prescription by blending novel technology, biometric feedback, and AI to positively impact the lives of many within non-surgical and mental recovery.

We're looking for Mid and Senior level Software Engineers with the motivation to join a Founding team and help build the future of wellbeing music tech.

You’ll be comfortable working across the stack (TypeScript, Next.js, Nest.js, infra/cloud) and be instrumental in shaping their architecture, tooling, and culture from day one. This is a unique chance to work hands-on with audio innovation, ML, and cutting-edge wellness experiences—all in a fast-moving, mission-driven startup.

Why this role stands out:

• You'll be a foundational team member of an incubated startup within a global business with extensive runway.
• Combine music, neuroscience, and machine learning—this is far from your typical SaaS.
• The tech challenges are greenfield: think ML-driven music personalisation, audio tooling, and scalable infrastructure.
• You’ll work directly with world-class musicians, scientists, and wellness experts.

The stage of the business means there's huge room for career progression with opportunities to take the lead on projects, define and design systems, create POCs, and work closely with their external clients. They're pragmatic, effective communicators and would like to bring someone in who has experience within startup environments.
